…And All Helicoprion Followed

This bizarre whorl-toothed shark was recently the subject of a new study that suggested its 100 or so teeth were fixed in place (as opposed to other sharks who use a conveyor belt-type system of replacement teeth); this suggested soft prey such as squid. Here the shark is trawling through a gathering of mating squid; it bears sucker marks and slashes (inspired by sperm whales) inflicted by its prey; the eye and single gill slit are modelled on ratfish and chimera that these sharks were thought to be more closely related to.
